Was sold GL4 oil, should I be worried?

[mr_magicfingers]

Bought a service kit which came with GL4 grade oil for the transmission and final drive. used it, but noticed in the book it says GL5 oil is the preferred grade for transmission and final drive.

Should I just ride it and use it till the next service, or do I need to change it earlier than that. I usually do the oils at 6000miles, or thereabouts.

Yes I know it's another oil question.

Change it now

Jus.

The reason GL5 is specified, is that it has additional qualities such as anti-foaming agents.
Also as St Eptoe has said many times, your bike is worth more than a £10 it would cost you for the correct oil.

I did the same a bit ago and the gearbox oil started to sort of pant out of the breather
Swapped it after I got some 5 OK since

I reckon it will be fine.... but then I put B&Q oil in the engine I've used GL4 and 5, sometimes together, and its been fine so far (90k)

Agreed, I assumed, obviously wrongly, that ordering a service kit from a reputable supplier would mean I'd get stuff that was per the spec. Next time I'll ask questions to make sure.

Most auto shops and garages stock GL5 and even the older K's specced it so it's a surprise that you received GL4.

Also, thought it was 75W - 140 in the final drive? and 75W - 90 inthe gearbox, anybody?

GL4 is for low to medium speeds and loads. GL5 has a much better shear strength. I've rebuilt loads of airhead gearboxes the wear in the gearboxes run on GL4 compared to those run on GL5 is noticeably higher for the sake of a few quid put the higher spec in.

Completely wrong.

The poster said it's GL4 spec. - So your wild GUESS would be incorrect.

The poster said it's GL4 spec..........

yep know what he posted, thought the EPX that I just got from Motoworks (which they recommend with the big service kit) said GL4 on the bottle so went and checked the Castrol spec.

I was wrong it doesn't say GL4 on the bottle but it does say GL5

.......... So your wild GUESS would be incorrect.

yup! my GUESS was incorrect and easily ignored by the OP, your point ?

My poiht ??? In case anyone else took notice of incorrect info - Some people don't read all the threads and just skim through them, as perhaps your good self did which lead to the additional last two posts and watsed both our time ).

If we see something wrong it should be pointed out, in case others not so informed take it as being correct.

Thats a fair point however my post though possibly incorrect for this thread, as a statement is correct regarding the EPX oil.......

 

[Stretchamus]

Completely wrong.

Mr Steptoe Sir, can you please enlighten me.

Best regards Stretch

I would not worry about GL4, it is entitled to exist, but I would not put it in my gearbox either, Halfords GL5 semi synth comes out at £9.99 last time I did the gearbox. I do fancy trying the Rock oil 20w50 semi synth next time though
